Lucia of Syracuse (283–304), also called Saint Lucia (Latin: Sancta Lucia) or Saint Lucy, was a Christian martyr who died during the Diocletianic Persecution. She is venerated as a saint in the Roman Catholic, Anglican, Lutheran, and Eastern Orthodox churches. She is one of eight women (including Mary) explicitly commemorated by Roman Catholics in the Canon of the Mass.
Her traditional feast day, known in Europe as Saint Lucy's Day, is observed by Western Christians on 13 December. Lucia of Syracuse was honoured in the Middle Ages and remained a well-known saint in early modern England.
